水泥石灰改良氯盐渍土强度特性试验研究
Experimental Research on the Strength Performance of Chlorine Saline Soil with Cement and Lime
摘要
Abstract
Composite improving program of cement and lime is selected to dispose of saline soil. The fall water of unconfined compressive strength is chosen to evaluate whether the improving program is good. The fall water of unconfined compressive strength test aims at improving saline soil of different improver doses and different curing age, and scanning electron microscopy (SEM) is used to analyze the micromechanism of improved saline soil. Finally the benefit-cost ratio method is applied to evaluate whether the improving program is economic. Comprehensively considering strength and economy, the improving program of 5% lime and 3% cement is recommended to choose.关键词
